IMPROVEMENT IN GRATES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES J. WOOLSON, of "Clevelend, Ohio, have invented a new and useful Grate for stoves. I make my grate with three or more movable bars of cast iron, which are rounded at the ends and form pivots which fit into journals in the frame (also of cast iron) which supports them. Armsare cast under the pivots on each bar, which fit into a link or stirrup which connects the bars with each other. lhe arms may be attached to one or both ends of the bars, as may be found desirable. One of the bars, projecting at one end beyond the others, is fitted to receive a winchwhich gives motion to them all. By forcing the winch to the right or to the left, as far as it will go, the bars overlap and close the spaces between them, and form an impervious fire-bed for the preservation of the fire when the stove is not in use. The east-iron frame upon which the ends of the grate-bars rest is also movable, having a pivot upon each end, with bearings upon the permanent main frame or bed-plate. With the same winch which gives motion'to the grate-bars, this frame, with the bars which it encloses, may be lifted from its usual bearings into another close beside it on the right, when another turn of the winch will dump the grate by turning over the frame; the pivot at the opposite end of the frame changing its hearing as the frame turns over, and returning to its place when the other is lifted into its original position.

The grate-bars are seen at D, in the drawing; the pivot-ends and journals at F; the arms at E; the link or stirrup at O; the projecting end of the bar for the winch at N; the movable frame at A; the pivots and bearings for the same at B; the duplicate hearing at S.

What I claim as my invention, and desire to secure by Letters Patent, is-

The tipping-frame A, provided with journals and bearings B, in combination with the shackle or grate-bar D, arms E. and link 0, and duplicate bearings S.
